Libraries and library organizations in the United States, as well as national, state, and regional policy planners are forced to rely upon outdated information about library cooperatives and networks due to a lack of valid definitions and inadequate data collection methods for these collaborative organizations. To rectify this problem, the American Library Association (ALA), Office for Research and Statistics, and the Association of Specialized and Cooperative Library Agencies (ASCLA), a division of ALA, will develop definitions for and classifications of library cooperatives.
